Checked the wire loom to the boot and it's fine. Swapped out the rear tail light bulb holders with another e90 and no joy, but, since I did that it cleared a heap of the light errors and left me with the original tail light warning.

So went got it read off and it came back with FRM error and even described my exact fault so I'm guessing it's common enough getting though my mechanic hasn't done one before.

When I called up bmw for a quote for a replacement the lad said they have a few of these of late in the dealers.

It seems you can replace with a second hand one but the prob is the LCM holds VIN and mileage details so would need syncing up with my car. If you don't do tis your left with a red do to the odometer to show mileage tampering :-( which I'd prefer avoid.

The joys of BMW motoring!
